Abstract (en)

A gear train comprises a frame (3) and a first central gear (15), a first planet gear (16', 17', 31) and a second planet gear (18, 32), which are each rotatably mounted to the frame (3) and extend in a first plane. The first central gear (15) is drivably coupled to the first and second planet gear (16', 17', 18, 31, 32). The gear train further comprises a second central gear (12, 25), a third planet gear (16", 17", 28) and a fourth planet gear (22, 33), which are each rotatably mounted to the frame (3) and extend in a second plane being parallel to the first plane. The second central gear (12, 25) is drivably coupled to both the third and fourth planet gear (16'', 17", 22, 28, 33). The first and third planet gears (16', 16", 17', 17", 28, 31) are fixed to each other and rotatable with respect to the frame (3) about a common first axis of rotation. The second and fourth planet gears (18, 22, 32, 33) are resiliently coupled to each other and rotatable with respect to the frame (3) about a common second axis of rotation.
